今天囉唆了點，不過一次寫一寫吧，插兩條跑雙通道有沒有差？
測試結果顯示是有的，跑hdparm測試硬碟效能時發現，
當只插一條原廠256MB DRAM時，結果為
/dev/sda2:
Timing cached reads: 4120 MB in 2.00 seconds = 1600.21 MB/sec
Timing buffered disk reads: 138 MB in 3.24 seconds = 59.64 MB/sec

插兩條512MB MEM1 2時，結果為
/dev/sda2:
Timing cached reads: 4240 MB in 2.00 seconds = 2120.32 MB/sec
Timing buffered disk reads: 182 MB in 3.00 seconds = 60.66 MB/sec

插三條512MB*2 MEM1 2，256MB MEM3時
/dev/sda2:
Timing cached reads: 3488 MB in 2.00 seconds = 1744.27 MB/sec
Timing buffered disk reads: 182 MB in 3.00 seconds = 60.60 MB/sec

插三條512MB*2 MEM1 2，256MB MEM4時
/dev/sda2:
Timing cached reads: 3520 MB in ...
